LOCIK Application sied october s, 1927. seriai No. 224,784.

This invention relates to a lock intended for use upon chests, drawers, doors or any other article wherein a locking device is required. The object of the invention is to provide a lock of simple, yet sturdy construction, which may be made in many pleasing ornament-al forms; which is so constructed that the same may be attached by anyone without any particular skill in 'carpentry and v1U which, when attached cannot be removed so readily or broken surreptitiously.

Vith these objects and such other objects as may hereinafter appear, in view, I have devised the particular arrangement of parts p described below andparticularly pointed out inthe claim appended hereto.

, Reference is to be had to the accompanying drawing, forming a part hereof, in which Figure l is a front elevation of my im- VK proved lock; I

Figure 2 is a sectional viewy on the line 2-'-2 of Figure l, looking in the direction of the arrows, the lock mechanism and bolt not being shown in section in order to more read- V ily disclose the construction of the important elements of the device;

Figure 3 is a front elevation of the lock with the casing or cover member swung away from the attaching plate and keeper; and

Figure 4 is a sectional view on the line 4 4 of Figure l, looking in the direction of :Mee of furniture directly above the drawer. If

yto a drawer l, 3 indicates a flat metal attach- 0 ing plate, which is secured against the outer face' of the drawer l by means of a plurality of screws 4 or other similar fastening members. The plate 3 may be of any suitable form, this being dependent upon thegeneral shape in which the lock is to be made and said plate 3 is provided with an extended or depending lower end 5 which terminates in a hinge 6. Said hinge 6 engages with the sloped lower end 7 of a cover member or casing 8. This cover member or casing 8 is so shaped that it completely covers the plate 3 and encloses the same by means of its integrally formed peripheral flange 9. The upper end of the casing 8 is extended well above the upper edge of the rplate 3 as shown at 10 and said extended part 10 of the casing 8 is adapted to t over and enclose a keeper attachment plate 1l.v Said keeper attachment plate 11 is secured to the fixed part 2 of the articleof furniture by means of securing screws 12 or other similar fastening means.

It will be seen from the foregoing that when the lock is in its closed position, as is disclosed in Figures l and 2, the casing 8 completely encloses all operating parts and provides an extremely smooth and finished appearance to the lock. It also provides a substantially large area, which may be orna inented in variousways to match the article of furniture to which the lock is adapted to be attached.

Thev lockvmechanism is shown at 13, the same being contained within the conventional metal casing or container and this is secured to the inner face of the casing 8 in any suitable way as by attaching screws 14. These screws 14 are preferably so attached that they thread into the inner side of the casing 8 and are neither visible nor accessible 17 secured to or integrally formed on the l plate 11. A similar U-shaped retaining member 18 is formed at the upper end of the plate 3 and the same is adapted to register with the part 17 so that-the bolt 16 may be I claim: A lock having a securing a casing pivotally attached to said plate and enclosing the keeper, a bolt for engagement with the keeper, andV means on the securingY plate constantly engaged by the bolt tohold the casing in a position to'cover. its securing plate when the lock is either 1n Vits closed or open position.

projected through both of the parts `17 and Y 18 to retain the lock in closed position as is shown in Figure 2 The lock mechanismrvv is so arranged that when the bolt 16 is withdrawn from the keeper member 17 and the lock is thus in its open position, said bolt member can only, by manipulation of the key,

be withdrawn a short distance and will retain its positionwithin the member 18 as is indicated in dotted lines in Figure 2. The lock mechanism for performinggthis function is not disclosed in detail since mechanisms of this typefare quite common and any one Of the well known kind may be used. The retention of the bolt 16 within the member 18 holds the casing 8 and the plate 3 in their completely connected position. VVhen it is desired to secure access to the lock mechanism 13,'the linger or a suitable tool may be inserted from the rear of the casing 8 and l the bolt member 16imay be pressed down so that it is completely withdrawn out of the member 18. Thereupon the casing 8 may be swung downwardly on its hinge 6 as dis.- closed in Figure 3 so that the lock mechanism is accessible and the attaching plate 3 is uncovered. y

i It .will be seen from the foregoing', that when the lock is in itsvclosed position, all fastening means,such as the attaching screws l and 12, and the lock mechanism screws 14 are completely covered by the casing 8. Thus, the unauthorzied tampering with the lock is prevented. The lock is also so constructed that no parts of the article of furniture to which it is to be attached need be 1n any way cut or mutilated for thel purpose of securing the lock in position. The casing 8 is also so formed that the complete lock is ofthe external type and said casing may be highly ornamented and so formedthat the lock, instead of detracting from the appearance of the article of furniture, will greatly aid its appearance.

Having described one embodiment of my invention, is obvious that the same is not t0 be restricted thereto, but is broad enough to cover all structures coming within `the scope ofthe annexed claim.
